Flores, a San Antonio Water System spokesman, said the ice bucket challenge's local water usage is relatively small and isn't really on SAWS' radar. "This kind of activity is for a very good cause," Flores said. "Our efforts are concentrated on sprinkler systems which can use to five to six hundred times more water than what these challenges are using."

SAN ANTONIO – The Ice Bucket Challenge certainly is all the rage right now. The latest participant? President George W. Bush, but not without hesitation.

In a video posted on his Facebook page this morning, Bush decided to write a check to the ALS Association, saying, "To you all who challenged me, I do not think it is presidential for me to be splashed with ice water, so I'm simply going to write you a check."

Then, his wife, Laura, bombards him with a bucket full of cold water, stating, "That check is for me, I don't want to ruin my hairstyle."

The former president accepted the challenge from his daughter Jenna Bush Hagar, golfer Rory McIlroy, businessman Woody Johnson and NFL Coach Jim Harbaugh.

Who's next? Bush challenged Bill Clinton.

"Yesterday was Bill's birthday, and my gift to Bill is a bucket of cold water," George Bush stated in the video.
